Berlin is pretty social ;)
This level: I'm done.
The combination is a cheap city full of life. If you have the chance you should definitely go check it out.
Just out of curiosity, how cheap would you say it is? Any crime issues?
Yes, great place to live or visit, full of life, great people, but not cheap.
Maybe you want to look further east.
Curious to know what is cheaper in Berlin compared with Copenhagen, I am surprised there is much difference. Did not find much difference in Denmark when I passed through, and spent quite a bit of time in Stockholm, avoided light beers. Did not find much that was more expensive.
